 I think the problem caused by the followings.
 
 In the file ports/lang/egcs/files/freebsd.h, 
 --------
 #define CPP_FBSD_PREDEFINES " -Dunix -D__FreeBSD__=4 -Asystem(unix) -Asystem(FreeBSD) "
 --------
 
 In the file ports/lang/egcs/Makefile
 --------
 pre-configure:
         @(MAJ=`sysctl -n kern.osreldate | ${SED} -e '/.....$$/s///'` ; \
         ${SED} -e "s:__FreeBSD__:__FreeBSD__=$${MAJ}:" ${FILESDIR}/freebsd.h \
                 >${WRKSRC}/gcc/config/freebsd.h )
 --------
 
 
 So, apply following patches to solve this problem.
